Apologies if this is a covered topic already, but I couldn't find what I was looking for in the archives.
I'm getting my hives ready for package arrival next week, and the beek I've been working with is out of town - so he's no help on this.
I'm wondering what size hole should be drilled, how many of them, and where, to improve ventilation?
The guy I've been working with drilled holes that look to be a bit less than an inch in diameter on the front & back of the top deep on his two-deep hives. Both holes (one front and one back) are above and offset from the handles.
Does this sound about right?
He drilled those holes with the bees in residence just before closing things up for the winter last November. I figured it would be easier to do it now while mine are empty. Is there any reason why I should wait?
Is there a reason why you wouldn't also ventilate the lower deep in this fashion as well?
